United States Patent O 3,111,tl96 DISPLAY DEVICE Aron Ernest Friesen, Monneal, Quebec, Canada, assigner to National Dairy Products Corporation, Chicago, Ill., a corporation of Delaware Filed Aug. 17, 1959, Ser. No. 834,274 1 Ciaim. (Ci. 163-115) This invention relates to display devices and it is of particular value for displays of the rotary type. Displays of this type, as used for adventising purposes, generally comprise a disc or turn-table, which carries suitable attentionaattracting pictures or other articles, often in color, designed to attract and hold the attention of the customer yor client of the establishment in which the display is located.

The principal object of the invention is to provide a device of the general character described, which is of light weight and readily movable and capable of being installed in any desired location and is capable of being positioned -at different angles.

Other objects and features will be apparent as the description proceeds. A preferred embodiment of the invention is disclosed in the accompanying drawings, in which:

FIGURE 1 is a plan view of the device in its horizontal position, i.e., with the axis of the turn-table vertical;

FIGURE 2 is a side elevation of the device, certain parts being removed to expose the operating mechanism;

FIGURE 3 is a plan taken on the line 3 3 of FIG- URE 2;

FIGURE 4 isa section taken on the line 4 4 of FIG- URE 3;

FIGURE 5 is an elevation of the turn table with its axis vertical, and with its supporting staff shifted to a vertical position, as indicated in the lower half of FIGURE 2; and

FIGURE 6 is an enlarged, fragmentary view showing the connection between the hub of the turn table and the driving #arbor of the device.

Referring to the drawings, the operating mechanism of the device, designated as a whole by the numeral 10, is positioned between the rotating table element 11 and the base plate element 12. The space between the plate 12 and the table 11 serves to house the motive power and its driving connection for rotating the display disc 11.

The base plate 12 of the device may be mounted on a pole or staff 13 slidably arranged in a sleeve 14 having a tangential extension 15 which, in the position shown in FIGURE 1 and in full lines in FIGURE 2, is substantially in alignment with the base plate 12. The tongue or extension 15 is connected to the plate -12 by a hinge element 16, the axis of which is located in a plane substantially perpendicular to the axis of rotation of the disc 11. Said hinge 16 permits the tubular sleeve or handle 14 to be swung down through an angle of about 90 into the position indicated in dotted lines at 14.

The base plate 12 is cut away beyond `the hinge element 16 so as to form a rectangular notch or opening 17 narrower than the pole 13, but just wide enough to permit the extension 15 to swing into line with the plate 12, as

shown in FIGURE 1, or at right angles thereto, as shown in `the dottedlines at 15 in said yFIGURE 2. l

On the inside of the base plate 12 there is mounted a stout sheet of insulating material 18 on which there are 6 mounted a pair of dry cells 19 and 19' (see FIGURE 5) andan electromagnet having a pair of coils 20' andra yoke terminating in pole pieces 21 which serveto energize and v drive a star-shaped rotary armature 22 on -a shaft having a pinion which, through reduction gearing designated 23 ice as a whole, drives a vertical shaft 24 at a speed of a few rpm., whereas the motor armature 22 operates at a much higher speed.

The slow speed shaft 24 is mounted in suitable bearings which maintain it perpendicular to the plane of the plate 12. The upper part of the shaft 24 ts Within a sleeve 25 or hub projecting vertically from the underside of the turn table `11. As indicated in FIGURE 6, the lower end of said sleeve 2S is provided With diametrically disposed notches 26 of suitable size to engage the projecting ends of a diametric driving pin 27 which is xed in the slow speed shaft `24. The extreme outer end 28 of the shaft 24 (see FIGURE 5) is threaded so that after the sleeve 25 has been lowered on the shaft 24 to engage the notches 26 with the ends 27 of the 'driving pin, a nut 29 on the outside of the turn table 11 can be screwed down to hold the sleeve or hub 25 of the disc 111 in driving engagement with the shaft 2'4.

It will be seen that the device disclosed is `fully portable; it is selfcontained and can be powered by a pair of small dry cells mounted within the device. If desired, by the use of a self-starting motor, the rotation of the disc may be started by means of a simple switch.

The hinge connection between the sleeve or handle and the base permits the device to be operated as a turn table rotating on a generally vertical axis, or on any desired angle to the vertical. The pole 13 is the sleeve I:14 may be adjusted and swung at any angle to the base to suit different requirements. In the full line position shown in FIGURES 1 and 2, the device can be 'placed upon a dat horizontal support with the disc axis vertical and with the handle 14 resting horizontally on `the support. In the position shown in dotted lines in FIGURE 2, the pole 13 is sl-id upwardly in the sleeve 14 so that its upper end is engaged by the margins of the slot 17 in the plate 12. The device is then, in effect, xedly positioned by the top of the pole by reason of the fact that its center of gravity is located to the right of the hinge 16 and vertically above the top of the pole.

Various of the features of the present invention believed to be new are set forth in the following claim.

I claim:

A means yfor supporting a portable display device, which display device includes a turntable and electric motor for driving the turntable, said means comprising a base plate upon which said display device may be mounted, said plate having a slot extending into said plate trom its perimeter, a handle for supporting said base plate, said handle being provided with a tongue adapted to occupy said slot and having its end hinged to said plate at the interior end of said slot and on an axis approximately parallel to the plane of said plate so that said tongue is capable `of being moved to a position substantially within said plane, and a pole slidable in said handle, whereby said handle may be positioned with its axis approximately normal to the plane of said plate, or with its Vaxis substantiallly parallel to the plane of said plate, the latter position providing a relatively flat surface on the lower side Iof said plate adjacent said slot.
